And please show steps.

[25 points The switch S is closed at time 1. L.a. A capacitor is initially uncharged in a series RC circuit. t 0 sec. If we double the voltage V of the emf source, which of the following statemernt true? s is tj The capacitor will charge in half the time. [ti] The capacitor will take twice as long to charge. [ti] The total energy stored in the capacitor (when fully charged) will quadruple. [b]-The initial current at t = 0 will quadruple. ] The total energy stored in the capacitor will double.

Explanation / Answer

1. Time constant is independent of voltage, T = RC , it is incorrect

2. Same logic

3. Total energy = 1/2 CV^2, hence it is correct.

4. Initial current = V/R, so current will double, it is incorrect

5. False as per 3
